I've spied myself a set of 41mm Keihin FCR's that might be suitable for my R1. The problem is the R1 requires a a throttle position sensor (TPS) and I don't think the carbs have one fitted.
1. Does anyone now if you can retro fit a TPS to the carbs and/or if it is economically feasable to do so?
2. Is it a worthwhile punt to buy second hand who-nows-how-worn FCR's? (my missus old GSXR750WN had worn flat slides and it was a bitch, spluttering off idle, even after dyno tuning)
Any Keihin FCR advice would be much appreciated.
